The USA economy is much worse than Greece's economy. Americans are generally much poorer with a much lower standard of living than people in Greece.

The NBA plays in front of 18,000+ fans for regular season games. The Greek championship was played in front of 0 fans. It's like comparing the heavy weight championship to a back alley brawl.

The Greek basketball league is a joke. No self-respecting star would lower himself to play in such a third world league. No wonder the NBA does not even play exhibitions games there. The NBA is for the 1st world only.
